A newly discovered set of mathematical equations describes how to turn any sequence of random events into a clock, scientists at King’s College London reveal. The paper is published in the journal Physical Review X. […]
Quantum 9, 1857 (2025). https://doi.org/10.22331/q-2025-09-11-1857 Many promising quantum applications depend on the efficient quantum simulation of an exponentially large sparse Hamiltonian, a task known as sparse Hamiltonian simulation, which is fundamentally important in quantum computation. […]
Quantum 9, 1856 (2025). https://doi.org/10.22331/q-2025-09-11-1856 We present BAE, a problem-tailored and noise-aware Bayesian algorithm for quantum amplitude estimation. In a fault tolerant scenario, BAE is capable of saturating the Heisenberg limit; if device noise is […]
Quantum 9, 1855 (2025). https://doi.org/10.22331/q-2025-09-11-1855 Highly correlated biphoton states are powerful resources in quantum optics, both for fundamental tests of the theory and practical applications. In particular, high-dimensional spatial correlation has been used in several […]
Quantum 9, 1854 (2025). https://doi.org/10.22331/q-2025-09-11-1854 We consider the extent to which a Trotterized time evolution implemented on a quantum computer is altered by the presence of decoherence. Given a specific set of assumptions regarding the […]
